Stacking of Quantity and Charge Adjustments Policies can cause negative charges

Affected versions

All versions of Exivity

Description

When creating two Absolute Discount Adjustment Policies, where both Policies apply to the same Account, Service and date Period, there is a chance of generating negative charges for the services where both Adjustment Policies apply to as can be seen in the following screenshot:

Workaround

The current workaround is to avoid stacking multiple Absolute Adjustments for each unique Account + Service combination. Instead, try to combine them within a single Adjustment Policy

Exivity Backend Service does not start / access to merlin.exe has been denied

Affected versions

Exivity version 3.5.0 and higher

Description

Some Anti-Virus software vendors (specifically: McAfee and APEX) incorrectly flag the Exivity binary merlin.exe as a backdoor/trojan horse. As a result, the Exivity Backend Service might not be able to start as shown in the example below:
Backend Service might not be able tostart
The Windows event viewer may display the following error (depending on your A/V vendor):
A/V software may deny access to merlin.exe

Resolution

Response by certain A/V vendors:
[merlin.exe] is detected by [a coupe of] AV's as a BackDoor as it's functionality is very similar and malware authors can use this to their own advantage to compromise systems and gather sensitive system information.
We also understand that [merlin.exe] can be used for legitimate purposes and therefore we will change the classification of the sample submitted to PUP. This way will be able to exclude detection through our scanner configuration but at the same time we are still protecting our customers who may be not be aware of this software running on their systems.
Hence if you want to allow this application in your environment kindly exclude it by detection name.
